Air Ministry Aircraft Radio Installations


Last updated: 8th June 2009

Here is my attempt to compile a list of the Air Ministry installation numbers listing the equipment used by the installation.
WWII military aircraft equipment is mainly built in a modular fashion, so that power units, aerial connections, control panels etc. could be varied according to the detail of the installation, which was given an ARI number.

I have compiled this list from many sources and it will contain errors.
Sources include: equipment that I own, museums, photos on eBay, Air Publications and other web sites.
If you find any errors or additions then please email...

See also my list of Air Ministry equipment numbers.
